Subject: linux-next: build failure after merge of the drm-misc tree

Hi all,

After merging the drm-misc tree, today's linux-next build (x86_64
allmodconfig) failed like this:

Caused by commit

  b6dcaaac4474 ("drm/vblank: _ioctl posfix for ioctl handler")

interacting with commit

  d5288c88c67c ("switch compat_drm_wait_vblank() to drm_ioctl_kernel()")

from Linus' tree.

You should consider rebasing your branch onto v4.13-rc1 (or merging
v4.13-rc1) so that these (unnecessary) conflicts don't keep happening
during development and the next merge window.

I have applied the following merge fix patch for today.
